This website started out as an attempt to list and categorise all known Roman Provincial coin bearing the image of Diadumenian. Over the years this goal has changed and it has become an online reporitory of my different collections. I have sold off most of my Diadumenian collection (I still have some) so I have changed the references to "Ex collection" where appropriate. As of August 2026 I am reworking this front site to be more modern (upgrading to HTML5) but all of the other sections should already be in the more modern format. This first page is therefore a work in progress but should be completed within a month or so. I also made the decision to have all the images on the one page rather than many subdirectories requiring clicking - the interneed speeds are now enough to cope with this.

While most reference works examining the output of Roman provincial coinage usually consider the mint as the axis around which other factors turn, that was not an approach which appealed to me, as my interest lay in examining the iconography of Diadumenian across the Roman-influenced world. Published works are, of course, invaluable and where appropriate have been referenced, but these references are disparate and it is expensive to obtain a complete listing for Diadumenian from current sources as there are often only a few relevant coins in each publication. Therefore, within this site, I have given previous published references where possible. Increasingly, reference material is available online and freely accessible and these sources have also been used extensively. Quality control with online sources can be an issue, but with care and attention a great deal of information can be gleaned there.

There are no silver coins in the collection, but these have been covered thanks to Michel Prieur, who has allowed me to include examples from his database.

I have not attempted to place values on any of the coins as there are freely available online sources which will give better and more current guidance in this area. Generally speaking, good quality examples from the non-Moesia Inferior or Thracian Provinces are scarce or rare, and values would be comparable to other similar scarce coins of those mints.

I hope this is of interest.
